Detailed Description

This class provides output methods to externalize values, and C-style arrays of values, of the fundamental integral and floating-point types, as well as bsl::string values. In particular, each put method of this class is guaranteed to write stream data that can be read by the corresponding get method of bslx::ByteInStream. See the bslx package-level documentation for the definition of the BDEX OutStream protocol.

See bslx_byteoutstream

Constructor & Destructor Documentation

◆ ByteOutStream() [1/2]

bslx::ByteOutStream::ByteOutStream	(	int	versionSelector,
		bslma::Allocator *	basicAllocator = `0`
	)

inlineexplicit

Create an empty output byte stream that will use the specified (compile-time-defined) versionSelector as needed (see {Versioning}). Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. Note that the versionSelector is expected to be formatted as "YYYYMMDD", a date representation.

◆ ByteOutStream() [2/2]

bslx::ByteOutStream::ByteOutStream	(	int	versionSelector,
		bsl::size_t	initialCapacity,
		bslma::Allocator *	basicAllocator = `0`
	)

inline

Create an empty output byte stream having an initial buffer capacity of at least the specified initialCapacity (in bytes) and that will use the specified (compile-time-defined) versionSelector as needed (see {Versioning}). Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. Note that the versionSelector is expected to be formatted as "YYYYMMDD", a date representation.

◆ ~ByteOutStream()

bslx::ByteOutStream::~ByteOutStream ( )

inline

Member Function Documentation

◆ bdexVersionSelector()

int bslx::ByteOutStream::bdexVersionSelector ( ) const

inline

Return the versionSelector to be used with operator<< for BDEX streaming as per the bslx package-level documentation.

◆ data()

const char * bslx::ByteOutStream::data ( ) const

inline

Return the address of the contiguous, non-modifiable internal memory buffer of this stream. The address will remain valid as long as this stream is not destroyed or modified. The behavior of accessing elements outside the range [ data() .. data() + (length() - 1) ] is undefined.

◆ invalidate()

void bslx::ByteOutStream::invalidate ( )

inline

Put this output stream in an invalid state. This function has no effect if this stream is already invalid.

◆ isValid()

bool bslx::ByteOutStream::isValid ( ) const

inline

Return true if this stream is valid, and false otherwise. An invalid stream is a stream for which an output operation was detected to have failed or invalidate was called.

◆ length()

bsl::size_t bslx::ByteOutStream::length ( ) const

inline

◆ operator const void *()

bslx::ByteOutStream::operator const void * ( ) const

inline

Return a non-zero value if this stream is valid, and 0 otherwise. An invalid stream is a stream for which an output operation was detected to have failed or invalidate was called.
